Most cubs have an O290, O320, or O360 engine all of which (I believe) are rated at 100% at 2700 RPM (no doubt I will be slapped with a wet noodle if I am wrong, and I am ready).
This means that the following (rough) table applies to all of these engines
Power % - RPM
95- 2675
90- 2600
85- 2550
80- 2500
75- 2450
70- 2400
65- 2350
60- 2250
55- 2200
50- 2125
Where do you run your cruise RPM at?
I was told with the borer you can run it higher, but it seems to me it still wears the engine as much as without...
